The name Dada, reputedly selected at random by sticking a knife in a dictionary, was adopted to symbolize the antirational, anarchic and anti-traditionalist stance of its members. The idea was to demolish bourgeois standards in the arts by mocking them. The Dadaists printed nonsense poetry set in a random selection of typefaces, exhibited such â€˜found objectsâ€™ as Duchamp\'s Fountain of 1917 (a urinal signed â€˜R. Muttâ€™) or a bicycle wheel mounted on a stool, and performed anti-music consisting of rude noises and random shouts. Such tactics of shock and unreason challenged accepted values in the arts (such as the cult of beauty), which the group regarded as hypocritical and out of keeping with 20th-century militaristic and industrial civilization.
